Salary sacrifice is one of the best ways to build your pension as a contractor. Through your umbrella, you agree to give up part of your gross pay. That amount goes straight into your pension before tax or National Insurance touches it.
DASA Umbrella holds dual accreditation from both FCSA and Professional Passport. Talk to us to set up or adjust salary sacrifice on your account.
What is salary sacrifice for umbrella contractors?
Salary sacrifice for umbrella contractors means agreeing to reduce your gross pay by a set amount each pay period. Your umbrella sends that amount directly to your pension provider before calculating your income tax and NIC. You pay less tax and NIC because your taxable gross is lower.
This is different from making a pension contribution from your net pay. With net pay contributions, tax and NIC come out first. With salary sacrifice, they never apply to the sacrificed amount at all.
Your umbrella handles the mechanics. You agree the sacrifice amount. It appears as a deduction on your payslip before the tax calculation runs.
How does salary sacrifice save you tax and NIC?
Salary sacrifice reduces your gross pay before PAYE and National Insurance are calculated. That means you pay income tax and employee NIC only on the lower gross figure. At basic rate, every £100 sacrificed saves around £28 compared to contributing from net pay.
Here's the breakdown at 2026-27 rates for a basic-rate taxpayer:
Without sacrifice: earn £100, pay 20% income tax (£20) and 8% employee NIC (£8). You contribute the remaining £72 to your pension.
With salary sacrifice, £100 goes straight to your pension. You pay no income tax and no NIC on it. The saving is £28 per £100 sacrificed.
At the higher rate (40% income tax), the saving is even larger. Every £100 sacrificed saves £40 income tax plus £8 NIC = £48 saved per £100.
Check the DASA pay calculator to model your own sacrifice scenario.
How much can you sacrifice through your umbrella?
You can sacrifice any amount above zero, up to the point where your remaining pay hits the National Minimum Wage floor of £12.71/hour. Beyond that floor, you cannot sacrifice further. The annual allowance for all pension contributions is £60,000 per tax year.
Your umbrella calculates your NMW floor based on your contracted hours. Once the floor is known, the maximum sacrifice amount is clear. Most contractors at day rates above £200/day have significant headroom.
The annual allowance is £60,000 or 100% of your earnings, whichever is lower. It rarely limits contractors unless you're making very large top-ups. Check with a financial adviser if you're close to this limit.
How does NMW limit your salary sacrifice?
After salary sacrifice, your effective hourly rate of remaining pay must still equal or exceed £12.71 per hour. Your umbrella applies this floor automatically. It will not process a sacrifice that takes your pay below this level.
Here's how the floor works in practice. Take a contractor working 40 hours/week. NMW floor = 40 hours x £12.71 = £508.40/week minimum remaining pay.
At £700/week gross pay, the maximum sacrifice is £700 minus £508.40 = £191.60/week. The umbrella can process up to that amount.
If gross pay is £520/week, the maximum sacrifice is just £11.60/week. At very low assignment rates, sacrifice becomes almost impossible.
At higher rates the floor is rarely a constraint. At £350/day, gross pay runs at roughly £1,498/week. That leaves significant sacrifice headroom above the NMW floor.
One more thing: salary sacrifice reduces your gross pay. Benefits like Statutory Maternity Pay and Statutory Sick Pay use gross pay as their basis. Sacrificing heavily reduces those entitlements. Factor this in before increasing your sacrifice.
A worked example at 2026-27 rates
Basic-rate taxpayer, 40 hours/week, £800/week gross pay after umbrella costs. Sacrifice amount: £100/week.
Without salary sacrifice:
| Item | Amount |
|---|---|
| Gross pay | £800.00 |
| Income tax (20% above weekly allowance) | -£100.54 |
| Employee NIC (8%) | -£48.20 |
| Employee pension (5% auto-enrolment) | -£26.46 |
| Net pay | £624.80 |
| Pension pot this week | £26.46 (employee) + £15.88 (employer) = £42.34 |
With £100/week salary sacrifice (on top of auto-enrolment):
| Item | Amount |
|---|---|
| Gross pay before sacrifice | £800.00 |
| Salary sacrifice | -£100.00 |
| Taxable gross | £700.00 |
| Income tax (20% above weekly allowance) | -£80.54 |
| Employee NIC (8%) | -£40.20 |
| Employee pension (5% auto-enrolment on lower base) | -£23.15 |
| Net pay | £556.11 |
| Pension pot this week | £123.15 (employee inc. sacrifice) + £13.88 (employer) = £137.03 |
The net pay drops by £68.69. But the pension pot grows by £94.69 more. You give up £68.69 in take-home pay. But £94.69 more goes into your pension. That's the efficiency of sacrifice.

How do you set up salary sacrifice with your umbrella?
Contact your umbrella and ask to set up salary sacrifice. Tell them the amount or percentage you want to sacrifice each pay period. They update your payroll records and the change appears from your next payslip.
With DASA, you call or email the payroll team. We confirm the maximum sacrifice allowed under your NMW floor and set it up. It typically takes one pay cycle to process.
You can change or stop the sacrifice at any time. Ask us to adjust it whenever your rate or working hours change.

What to watch out for
Three things to check before increasing salary sacrifice: your NMW headroom, the impact on statutory benefits, and your annual allowance. Get all three confirmed before you set a higher sacrifice amount.
NMW headroom is your gross pay minus the NMW floor for your hours. Your umbrella calculates this. Ask for it in writing.
Statutory Maternity Pay and Statutory Sick Pay use your post-sacrifice gross as their base. So does Statutory Paternity Pay. Sacrificing heavily reduces what those benefits pay out.
The annual allowance is £60,000 for 2026-27. If total pension input exceeds this, you face a tax charge. Total input includes sacrifice, employer contributions, and any personal top-ups. For most contractors this limit is far higher than their total contributions.

FAQ
What is salary sacrifice for umbrella contractors?
You agree to reduce your gross pay by a set amount. Your umbrella sends that amount to your pension before tax and NIC are applied. You pay less income tax and employee NIC because your taxable gross is lower.
How much tax does salary sacrifice save through an umbrella?
At basic rate (2026-27), every £100 sacrificed saves approximately £28: £20 income tax plus £8 employee NIC. At the higher rate, the saving rises to around £48 per £100 sacrificed.
How much can I salary sacrifice through my umbrella company?
You can sacrifice up to the point where your remaining pay equals the NMW floor of £12.71/hour. Above that floor, you can sacrifice as much as you choose up to the £60,000 annual pension allowance.
How does NMW limit salary sacrifice through an umbrella?
After sacrifice, your remaining pay must still meet the NMW of £12.71/hour for your contracted hours. Your umbrella calculates this floor and stops sacrifice at that point. At higher day rates there's usually significant headroom.
Does salary sacrifice affect statutory benefits?
Yes. Statutory Maternity Pay, Statutory Sick Pay, and Statutory Paternity Pay are based on gross pay after sacrifice. Sacrificing a large amount reduces what those benefits pay out.
How do I set up salary sacrifice with DASA Umbrella?
Contact the DASA payroll team, tell us the amount you want to sacrifice each pay period, and we set it up. The change appears from your next payslip. You can adjust or stop it at any time.
